An update on the issue I am facing: We have a static html in web server called signon.html. Users access this static html page first which has a refresh directive with content=1. As soon as the user invokes this html page first time from the origin, this redirects to a login form page. This response contains the header too. But still chrome console says the origin was in origin-keyed cluster. If I change the refresh directive content=5, it takes 5 sec to redirect from signon.html to login form, this time I don't get the console warning. Now I can login and dont see any errors. I am not sure why the refresh directive 5 works but not 1. Is it because Chrome could not capture request and place the origin in appropriate cluster within its 1 second?
Modified the CONTENT=5 from CONTENT=1 in the below line to get it working - <meta HTTP-EQUIV='Refresh' CONTENT='5; URL=../psp/ps/?cmd=login'> Any thoughts?

My existing tab did not throw this error whereas the new tab shows the error on the first request itself. So based on what you mentioned, my parent tab should have been part of Origin-Keyed cluster, right? I am seeing console warning as follows on my new tab that was opened from an existing tab: "The page did not request an Origin-Keyed agent cluster but was put in one anyway because the origin had previously been placed in an origin-keyed agent cluster. Update your headers to uniformly request origin-keying for all pages on the origin" I am currently trying to figure out which server response did not have the header ""Origin-Agent-Cluster: ?0" that led my pages to get in origin-keyed cluster. Is there a way (debug tool etc) I can check which response decided Origin-Keying? I think this will be crucial for applications to debug the issues. One other question: My parent tab has a wss (web socket) request that does not have its response with this OAC header. Do we need the header in wss response as well?

Essentially, the first time the tab loads anything from a particular origin, that determines how it will treat the origin for the remainder of the tab's lifetime. This consistency will also extend to other tabs opened by the tab (as they live in the same "BrowsingInstance"). Also, there may be issues where pages can be loaded from cache without the ?0 version of the header, so two useful steps would be 1) Clear the cache, and 2) open the app directly in a newly opened tab. I don't think the header needs to be sent on script/css/image requests, as they're used within the context of the .html resource that should have the header. [image: GoogleAnimated.gif] ⭘ W.

I have some of the customers reporting inconsistent behavior. Our application sends "Origin-Agent-Cluster: ?0" in response headers to opt-out of Origin Agent clusters since we rely on document.domain. Is this header needed only on document requests or even for script, image, css requests? For some customer, their pages get inside origin-keyed cluster even though the responses contain the header "Origin-Agent-Cluster: ?0". Is there a bug in the chrome behavior that puts pages in specific cluster? How do we debug what caused the pages to get inside origin-keyed cluster?

The important thing here is that it does not break document.domain setting and subsequent cross-origin access, but that instead -- if the conditions are just right; or arguably just wrong -- the app can get into a state where same-origin accesses are mistakenly blocked. Apparently an app can get into a state where frames within the same page are inconsistently assigned to agent clusters (i.e., frames in the same origin end up in different processes), and thus subsequent accesses within that origin may fail. My plan right now is to leave this on at 50% beta, but to not proceed to any stable releases at any percentage. I'll update this thread when I have a better handle on the bug and can suggest a good way to proceed.

The bug also affects pages that have not even set document.domain. Since I have now missed a substantial portion of the 109 beta cycle I'd like to delay the roll out once more, and shift it by one milestone (or two; depending on when everything is fixed). On the positive side: Recently the last of the previously identified big document.domain users, that together accounted for about 50% of remaining usage, has dropped their usage. So current usage is lower than previously reported. See the usage dip around late November at deprecate.it (1st graph).

This is that separate intent. A summary of what happened so far: - Shipping Origin Isolation by Default (and thereby deprecating document.domain) has security benefits, but compatibility risk. - We added warnings to the developer console and issues panel, published a blog post, and engaged in direct outreach. This has resulted in substantial, measurable reduction of usage. Some sites keep using document.domain, but have mitigated the deprecation with other means. This makes the risk difficult to measure. - Sampling of sites with document.domain usage and manual inspection yields a potential breakage estimate at ~0.015% of page views. What we're asking for here is: - Enable the feature at 50% for beta (+ dev + canary) during M109, as a "last call" for web site authors. This sounds like a good idea. Is there any reason we couldn't go to 50% in M108 as well (or are you trying to avoid breakage over the winter holidays)? No reason. I'd be happy to go to beta as soon as I receive the lgtms. I had conservatively budgeted that to be 109. :-) Another question: do we have enterprise policies available for this change? Yes; the policy is here: OriginAgentClusterDefaultEnabled <https://source.chromium.org/chromium/chromium/src/+/main:components/policy/resources/templates/policy_definitions/Miscellaneous/OriginAgentClusterDefaultEnabled.yaml> - Launch on stable on M110. (~ Feb '23, so >12 weeks out from today) ------------------------ Contact emails va...@chromium.org, voge...@chromium.org Specification Explainer: https://github.com/mikewest/deprecating-document-domain HTML Spec draft: https://github.com/whatwg/html/compare/main...otherdaniel:dd API spec Yes Summary This is a follow-on to the Intent to Ship: Origin Isolation By Default / Deprecate document.domain <https://groups.google.com/a/chromium.org/g/blink-dev/c/_oRc19PjpFo/>. We'd like to ship this in M110, stable. Summary (of the underlying change) Change the default behavior of the Origin-Agent-Cluster: header / document.domain settability. Presently, pages within Chromium have site-keyed agent clusters by default, unless the Origin-Agent-Cluster: header is explicitly set to true. This accommodates pages or frames which want to access each other's state, despite being on different origins (but within a site). This is fine for any pages that wish to do so, but because a page *might* set document.domain later on, Chromium currently must use site-keyed agent clusters for *all* pages by default even though the overwhelming majority of pages do not ever make use of this (mis-)feature. In turn, this requires Chromium to use sites as the basis for renderer process isolation (via Site Isolation), which exposes origins to same-site but cross-origin attacks involving compromised renderer processes or the "Spectre" family of side-channel attacks. This proposal changes the default behaviour of Origin-Agent-Cluster. From a developer's point of view, the new default matches "Origin-Agent-Cluster: ?1". The initial implementation will use origin-keyed agent clusters for all (non-opted out) origins, without changing how many processes Chromium creates. Over time, we can then adapt Chromium's isolation strategy towards origin-keyed processes without further affecting web-visible behaviour. The developer-visible aspect of this is that for pages with origin-keyed agent clusters, document.domain is no longer settable. Thus, we have marked this intent as a deprecation. Note that this proposal is about the default. Both modes - site-keyed or origin-keyed agent clusters - remain available to any site, but origin-keyed agent clusters change from opt-in to opt-out. The current behaviour remains available by setting "Origin-Agent-Cluster: ?0".

Activation - Deprecation plan M109: Enable "Origin Agent Cluster by Default" for 50% of page loads on beta, dev, and canary. M110: Enable "Origin Agent Cluster by Default" on stable.
